Understanding circuit breaker design and operation to improve safety and reliability in underground mining
Electronic LSI trip delivers precise protection and fast fault clearance, reducing arc flash risk and equipment damage. This is crucial for high-demand mining drives and conveyors where marginal faults escalate downtime and maintenance costs. The 600 A rating paired with 1000Y/577 Vac and 250 Vdc capability supports large motor loads and feeders, enabling fewer devices in a given panel and streamlined wiring. The magnetic trip range of 500-2500 A provides flexible coordination across multi-point protection schemes, improving uptime in complex mine networks. An undervoltage release of 120 Vac rear with a left pigtail enables reliable remote control and safer integration with plant automation. The three-pole L-frame Mining-class construction delivers rugged durability, high interrupt ratings, and compatibility with existing E2 footprints for straightforward retrofits. Rounding out the value, Eaton’s documentation and global certifications help validate compliance while a one-year to eighteen-month warranty supports total cost of ownership in rugged mining environments.

FAQs
Plan for a three-pole, L-frame installation with the unit configured as a complete E2LEM device. Ensure mounting provisions align with existing E2 MCCB footprints and verify the undervoltage release (120 Vac rear with left pigtail) is wired to the control circuit. The unit ships without terminals, so select compatible lugs or connectors per your panel design and torque specifications from the datasheet.
Key specs include a 600 A amperage rating, voltage rating of 1000Y/577 Vac and 250 Vdc, three-pole configuration, electronic LSI trip, and a magnetic trip range of 500-2500 A. It offers a robust interrupt capability across multiple voltages (65 kAIC at 240 Vac, 22 kAIC at 250 Vdc, among others) and is designed for mining-class protection.
Yes. The device is UL Listed, IEC Rated, and CSA Certified, ensuring conformance to widely recognized safety and performance standards for mining electrical protection equipment, both underground and surface installations.
Ideal for mining conveyors, feeders, motors, and other heavy-load equipment requiring reliable protection. Its high current rating and LSI trip support precise fault clearance, while the 1000Y/577 Vac and 250 Vdc capabilities address both AC and DC protection needs common in mineral processing and extraction facilities.
Eaton’s policy includes a one-year warranty from installation or eighteen months from shipment, whichever occurs first. The product ships with extensive documentation and is supported by Eaton’s service networks, including mining-specific safety and performance literature to aid maintenance and lifecycle planning.
